Specification of Letters Patent.

Patented Ju1y so, 1907.

Application liled March 21, 1907. Serial No. 363,621.

To all whom 'it Imay concern:

Be it known that I, ALLEN E. OSTRANDER, a citizen of the United States, residing atPaterson, New Jersey, have invented a certain new and useful Improvement in Car Construction, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to theA accompanying drawings, forming part of this specification, in

which .Figure 1 is a top plan view of a 4center sill construction embodying the features of my invention Fig. 2 is a side elevation of oneef the sills shown -in Fig. 1; Fig. 3 is a cross sectional View taken on the line 3 3 of Fig. 2; and Fig. 4 is a cro/ss sectional view taken on the line 4--4A of Fig. 2.

This invention relates to the construction of railway rolling stock.

The object of my invention is to provide a longitudinal sill construction such as is used in the underframe of a car, which can`be manufactured at a low cost, and which will be light, rigid, and capable of carrying great loads.

I have herein illustrated a center sill construction embodying the features of my invention, and referring to the drawings, 1 designates the webs oi the sill members, each of these webs being formed from pressed metal and provided at its upper edge with an `integral iiange 2 that projects outwardly. Secured to the lower edge oi each web 1 are two angles f8 that project in opposite directions, the webs 1 being riveted between the vertical legs of said angles, as shown in Fig. 4. Preferably, the lower edges of the webs 1 are sheared 0H to prpVide'a-sill of the sh-bellied type which is oi greatestdepth at the transverse center oi the car,

vas shown in Fig. 2. The top coverA plate 4 is secured to the integral ilange 2 at the upper edges'o the webs 1,

a point intermediate the body bolster 5 and end sill 6, vare draft sills 7 which are preferably channel shaped y and formed with webs having-laterally projecting angles along their lower-edgeportionsfand having commercially. rolled angles secured alongtheir upper edge portions with the flanges projecting outwardly. These draft sills are connectedto the center sills by means of splice plates 8 that are secured to the inside-faces oi the webs 1 ofthe center sills, as-shown in Fig. 3A

The center sill webs are 4formed from 'pressed steel,l

andthe angles secured tothe lower portion o'f'said" the center sill webs it should be understood that my invention is not limited to this exact construction, and if desired said angles may terminate at any convenient point between the deep partof the sill and the part near the bolsters.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A longitudinal car sill consisting of ,a pressed metal web plate provided at its upper edge with an integral flange, and commercially rolled members secured to the lower edge of said plate; substantially as described.

2. A longitudinal car sill consisting of a pressed metal web plate oi'. greatest depth at its center and provided at its upperedge with an integral laterally projecting liange, and commercially rolled members secured to the lower edge of said web plate throughout its entire length; substantially as described. Y

3. A longitudinal car sill consisting of a pressed metal web plate provided at its upper edge with an integral later` interposed between the vertical legs or angesof said members; substantially as described.

4. A. center sill for a car consisting of a pressed metal web plate that extends from-bolster to bolster of the car and having an integral flange at its upper edge, the lower edge of said web platebeing sheared olf so that said plate gradually diminishes in depth from its ,middle portion toward its opposite ends, and Acommercially rolled angles se- Vcured to the lower edge of said plate and having their horizontal legs projecting' as described.

5. In a center sill construction, pressed metall web plates extending from bolster: to bolster-of the car and having in tegral'oppositely projecting flanges at their upper edges, commerciallyyrolled angles secured near the lower edges of said plates, with the horizontal legs of said angles projecting in`opposit directions, and Achannel shaped draft sills.

6. vInra center sill construction,l pressed metalA web plates extending -from bolster to bolster, said web plates having oppositely projecting'A integral flanges, angles secured near `the lower edges-o said web lplates and draft sills connected in opposite directions; substantially with the end portions of said web plates, said draft sills` comprising channel shaped members formed with Weins each having'anintegral ange and an angley secured to eachv of saidwebs near the top edge thereof. v

'7.jIn combination, a center sill consisting of a pressed lmetal web plate deepest-at its middle portion and, l1av1ng an integral flange at its upperv side and a .commercially rolledangle securedl alongits lower caiga-.mnd a draft sill secured 'to' said center sil1,sa.idy draft sill consisting oiga.A

-welaportlon with `one integralnange and :z commermially rolled angle, forming a second flange, rsecured to said draft tal legs of the angles and the ilanges on the sill.

8. In Vasill constrction, center sills formed of flanged pressed metalweb plates `deeper at their middle portions than near the ends, commercially rolled angles secured along the loweredge portions of said -Web plates and channel shaped draft sills connected with the end portions of said center'sills, said draft sills comprising danged web plates with rolled angles secued thereto, with the horizonweb plates'pro- 1() jecting outwardly. v v

In testimony whereof I hereunto affix my signature inv the presence of tv'vo witnesses, this 12th day of March 1907.'l
